I'm looking at replacing solenoids based on the issues I posted on last week as insurance. I've gone back through my troubleshooting and believe that's where the issues stem from as both spool valves (one of which I replaced) were fine and I confirmed their operation independently as well as the switches.

That being said, I have two questions:
1) When I'm using Catbase, they often use phrases such as "starting from SN M-907...". The question is where in my VIN do I confirm that I am before or after that series? For reference, my VIN is 2P9M33400R1001774.

2) I found the part in Catbase and it shows what appears to be 1 part number for the entire bank of 5 solenoids. Does that mean that the part number represents 1 of 5 and I need to order a total quantity of 5 or is the one part number for a bank of 5 complete (therefore only needing to order one)?

I'm hoping that it's the latter as it seems that the cost is about $325 ea.
